POST FOR ELECTRIC CONDUC TORS.

SPECIFICATION forming part of Letters Patent No. 286,397, dated Getober 9, 1883.

Application filed May-7, 1853. (No model.)

To (0Z1? whom it may concern.-

IBe it known that I, J. ALLEX Dnrmx, a citizen ofthe United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Ioles or Iosts for Electric Conductors, of which the following is a specification.

My invention relates to certain improve ments in poles or posts for supporting electric lights, telegraphovires, &c., when the latter are used in connection wit-h underground cables or conductors, the objects of my invention being to permit the ready iormation of the connections between the conductors and the lamps or overhead wires, to provide for the proper direction and support of the wires, and to permit the ready testing of the same.

In the accompanying drawings, Figure 1 is a vertical sectional view of one form of my inr proved post adapted for the support of an electric light; Fig. 2. a vertical section of the post adapted for the support of overhead wires, and Figs. 3 and 4c enlarged views of parts of the post. I

A represents the post, which may be a cast-iron column or a wrought-iron tube, and may be in one piece or in as many sections as desired. The lower end of this tubular post is fitted to a hollow base, B, preferably of castdron, and is suitably secured thereto. From the base B projects a tube, D, which communicates with a box, F, sunk below the l evel ol' the street, and communicating through a tube, G, with the conduit carrying the wires or cables for conducting the electric current, the box F having a suitably-covered manhole, and being of such dimensions that the wires a: in running from the main conduit to the post will be exposed for a shortdistance between the tubes 1) and G, so as to permit of their examination and to facilitate testing.

The wires a (shown in Fig. I.) extend up inside of the post to the top of the same, where they are guided and supported by internal eyes, a, Fig. 3, and pass thencethrough downward]y-projecting tubes b on the sides of the post to the lamp, the standard of which is screwed into the top of said post, the downwardl'yu'ojecting tubes serving to prevent the access 01' rain or snow to the interior of the post.

In the present instance the base 13 has another laterallyproiecting tubular branch, I), through which the wires a may be run to a building in front of which the lamp is situated. The number of branches, however, is not essential. For instance, in Fig. 2 I have shown a base with but one branch, through which passes a cable, 1 carrying a number of telegraph-wires. W here the post is placed at the intersection of two or more underground conduits, it will have a number of tubular pro iections, one for each conduit.

The cable 12 extends up through the post, and is supported near the top of the same by a clasp, (I, carried by the eyes a, the different wires passing through the tubes 7) to the insulators on a crossbar, II, which is supported on the post by means of a suitable clamp. In this case the top of the post is closed by a screw-cap.

By making the hollow base I of cast-iron and closing the same at the bottom, the access of moisture at that point is prevented, this being an advantage over a base having a bottom joint, as it is desirable to keep the coin duetors as dry as possible.

I claim as my invention" 1. The combination of a hollow post with the hollow east-metal base I3, closed at the bottom, and having one or more laterallyn'ojeeting tubular branches, through which the wires enter the hollow post, as set forth.

2. The combination of the hollow post and the testing-box F with the hollow base B, having a laterallyproiccting tubular branch communicating with said testing-box, as setforth.

The hollow post A, having near the top internal eyes, c, for the support and guidance of the wires within the post, as set forth.

4-. The hollow post A, having near the top downwardlyproiecting tubes b for ihcpassage of the wires, as set forth.

In testimony whereof I have signed my name to this specification in the presence oi'twosubscribing witnesses.

J. ALLIED DIJVLIN.
